Electrical and Environmental Specifications
This section contains the electrical and environmental specifications for the 21145.
Caution:
Stresses greater than the maximum or less than the minimum ratings can cause permanent damage
to the 21145. Exposure to the maximum or minimum ratings for extended periods of time lessen
the reliability of the 21145.

Oscillator Characteristics
When driving the 21145’s integrated oscillator circuitry from an external clock source, an external
clock having the following characteristics must be used to ensure proper operation of the 21145:
Clock frequency: 20 MHz ±0.01% (100 ppm, TTL, or CMOS)
Rise/fall time: < 4 ns
Duty cycle: 40%–60%
